Everything in Java is ~~done~~ inside classes. Classes are bodies of statements, methods, and variables. A statement can be thought of as the smallest standalone element of an imperative programming language (or a language that explicitly specify an algorithm to achieve a goal, opposed to declarative programming, which explicitly specifies a goal and leaves the implementation of that goal to algorithms within the support software). A program is formed by a sequence of one or more statements (e.g. if x, then y). A statement will have internal components (e.g. expressions). A method usually consists of a sequence of statements to perform an action, a set of input parameters to customize those actions, and possibly an output value (called return value) of some kind. There is a method called main that all classes have. This is the start point of your program - where everything must begin. To create a class, the syntax (or basic outline in code) is:
